FIELD OF THE INVENTIONProcesses are provided for selecting, ingesting and/or purchasing foods for achieving weight control, as well as processes for producing food products, and systems and processes for assisting with each of the foregoing.
BACKGROUND OF THE INVENTIONWeight Watchers International, Inc. is the world's leading provider of weight management services, operating globally through a network of Company-owned and franchise operations. Weight Watchers provides a wide range of products, publications and programs for those interested in weight loss and weight control. With over four decades of weight management experience, expertise and know-how, Weight Watchers has become one of the most recognized and trusted brand names among weight conscious consumers.
Years ago, Weight Watchers pioneered innovative and successful methods for weight control and systems for assisting consumers in practicing such methods. Such methods and systems are the subjects of U.S. Pat. No. 6,040,531; U.S. Pat. No. 6,436,036; U.S. Pat. No. 6,663,564; U.S. Pat. No. 6,878,885 and U.S. Pat. No. 7,361,143, each of which is incorporated herein by reference in its entirety. These methods assign values to food servings based on their calorie content, which is increased on the basis of fat content and decreased on the basis of dietary fiber content. This assignment is carried out using a proprietary formula developed by Weight Watchers scientists. The values for food servings consumed each day are summed and the consumer ensures that they do not exceed a predetermined maximum value. These methods afford a simple and effective weight control framework, especially for those who cannot devote substantial attention to their weight control efforts.
This formula seeks to encourage consumption of dietary fiber by reducing the “charge” for foods ingested by subtracting an amount based on their fiber content. It does not, therefore, assign any calorie or energy value to fiber, but rather diminishes the perceived cost of consuming fiber-rich foods to induce consumers to prefer them.
For this application the following terms and definitions shall apply:

In certain embodiments, the food energy data is associated with the food product by including the food energy data on a substrate associated with the food product. In certain ones of such embodiments, the substrate comprises a package for the food product. In certain ones of such embodiments, the substrate comprises a label accompanying the food product.
Food servings can be specified in various ways, and preferably in ways that are meaningful to consumers according to their local dining customs. Food servings may be specified by weight, mass, size or volume, or according to customary ways of consuming food in the relevant culture. For example, in the United States it is customary to use measures such as cups, quarts, teaspoons, tablespoons, ounces, pounds, or even a “pinch”, in Europe, it is more common to use units such as liters, deciliters, grams and kilograms. In China and Japan it is also appropriate to use a measure such as a standard mass or weight held by chopsticks when consuming food.
In certain embodiments, food energy data is produced based on protein data representing the protein energy content of a candidate food serving, carbohydrate data representing its carbohydrate energy content, fat data representing its fat energy content, and dietary fiber data representing its dietary fiber energy content. This data is provided either by the consumer or from another source based on data from the consumer, such as food identification data. If the protein energy data is represented as “PRO”, the carbohydrate energy data as “CHO”, the fat energy data as “FAT”, and the dietary fiber energy data as “DF”, in certain ones of such embodiments, the food energy data (represented as “FED”) is obtained by processing the data in the manner represented by the following equation:
FED=PRO+CHO+FAT+DF. (1)
In certain ones of such embodiments, food energy data is produced based on the protein energy data, the carbohydrate energy data, the fat energy data, and the dietary fiber energy data, of the candidate food serving, by applying respective weight data to weight each of the protein energy data, the carbohydrate energy data, the fat energy data and the dietary fiber energy data representing its relative metabolic conversion efficiency and forming the food energy data based on a sum of the weighted protein energy data, the weighted carbohydrate energy data, the weighted fat energy data and the weighted dietary fiber energy data. If Wpro represents the respective weighting data for PRO, Wcho represents the respective weighting data for CHO, Wfat represents the respective weighting data for FAT and Wdf represents the respective weighting data for dietary fiber, in certain ones of such embodiments, the food energy data (represented as “FED”) is obtained by processing the data in the manner represented by the following equation:
FED=(Wpro×PRO)+(Wcho×CHO)+(Wfat×FAT)+(Wdf×DF). (2)
In certain ones of such embodiments, Wpro is selected from the range 0.7≦Wpro≦0.8, Wcho is selected from the range 0.9≦Wcho≦0.95, Wfat is selected from the range 0.97≦Wfat≦1.0 and Wdf is selected from the range 0≦Wdf≦0.5 In certain ones of such embodiments, Wpro is substantially equal to 0.8, Wcho is substantially equal to 0.95, Wfat is substantially equal to 1.0 and Wdf is substantially equal to 0.25.
In certain embodiments, food energy data is produced based on protein data representing the mass or weight of the protein content (represented as PROm), carbohydrate data representing the mass or weight of the carbohydrate content (represented as CHOm), fat data representing the mass or weight of the fat content (represented as FATm) and dietary fiber data representing the mass or weight of the dietary fiber content (represented as DFm), of a candidate food serving. In such embodiments, the protein data, carbohydrate data, fat data and dietary fiber data, are converted to energy data in producing the food energy data, by processing the protein data, carbohydrate data, fat data and dietary fiber data in the manner represented by the following equation:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×CHOm)+(Wfat×Cf×FATm)+(Wdf×Cdf×DFm), (3)
where Cp is a conversion factor for converting PROm to data representing an energy content of PROm, Cc is a conversion factor for converting CHOm to data representing an energy content of CHOm, Cf is a conversion factor for converting FATm to data representing an energy content of FATm and Cdf is a conversion factor for converting DFm to data representing an energy content of DFm. For example where the food energy data is represented in kilocalories and PROm, CHOm, FATm and DFm are expressed in grams, Cp is selected as 4 kilocalories/gram, Cc is selected as 4 kilocalories/gram, Cf is selected as 9 kilocalories/gram and Cdf is selected as 4 kilocalories/gram.
In the US and in CA, where food labeling standards include a food product's dietary fiber in its total carbohydrate amount in grams (represented as “Total_CHOm” herein), food energy data may instead be produced by processing the protein data, carbohydrate data, fat data and dietary fiber data in the manner represented by the following equation:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×[Total_CHOm−DFm])+(Wfat×Cf×FATm)+(Wdf×Cdf×DFm). (4)
In certain embodiments, the food energy data is produced in a modified fashion in order to discourage consumption of foods having a high saturated fat content, so that the food energy data (FED) is based both on the relative metabolic conversion efficiency of selected nutrients and weighting data that promotes consumption of relatively more healthful foods. In such embodiments, and where (as in the US and CA) food labeling standards include a food product's saturated fat (represented as “Sat_FATm” herein) in its total amount of fat in grams (represented as “Total_FATm” herein), the food energy data is produced by processing the protein data, carbohydrate data, fat data, saturated fat data and dietary fiber data in the manner represented by the following equation:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×[Total_CHOm−DFm])+(Wdf×Cdf×DFm)+(Wfat×Cf×[Total_FATm−Sat_FATm])+(Wsfat×Cf×Sat_Fatm), (5)
wherein Wsfat represents modified weighting data for Sat_FATm. In certain ones of such embodiments, Wpro is selected from the range 0.7≦Wpro≦0.8, Wcho is selected from the range 0.9≦Wcho≦0.95, Wfat is selected from the range 0.97≦Wfat≦1.0, Wdf is selected from the range 0<Wdf≦0.5, and Wsfat is selected from the range 1.0≦Wsfat≦1.3. In particular ones of such embodiments, Wpro is substantially equal to 0.8, Wcho is substantially equal to 0.95, Wfat is substantially equal to 1.0, Wdf is substantially equal to 0.25 and Wsfat is substantially equal to 1.3.
The relatively higher value assigned to Wsfat is based, in part, on the desirability of discouraging consumption of saturated fat, due to the ill-health effects associated with this nutrient. The higher ranges and values of Wpro and Wcho in the presently disclosed embodiments relative to those employed in embodiments disclosed hereinabove, are useful for weight loss processes. That is, consumers engaged in a weight loss process by limiting their food energy consumption could, in some cases, be encouraged to eat foods higher in saturated fat if it is assigned a relatively higher weight than other nutrients, since this tends to reduce their overall food energy consumption. By assigning relatively higher ranges and values for Wpro and Wcho for use in processes that also weight saturated fat higher than unsaturated fat, the potential to encourage consumption of saturated fat is substantially reduced. Accordingly, the weights assigned to Wpro and Wcho in the presently disclosed embodiments are based both on the relative metabolic conversion efficiency of protein and carbohydrates and the desire to promote consumption of relatively more healthful foods.
In certain embodiments, for foods containing alcohol, the foregoing processes are modified to add a term representing an energy component represented by the amount of alcohol in the food. Where the amount of alcohol (by weight or mass) is expressed in grams (represented as “ETOHm” herein), this term is produced by multiplying ETOHm by a weighting factor Wetoh and a conversion factor Cetoh, where Wetoh is selected from the range 1.0≦Wetoh≦1.3, and in particular ones of such embodiments is substantially equal to 1.29, and Cetoh is selected as 9 kilocalories/gram, based on the principle that alcohol is metabolized in the same pathway as fat. The higher value assigned to Wetoh is based, in part, on the desirability of discouraging consumption of alcohol, due to the ill-health effects associated with this nutrient. Where a food contains alcohol, in certain embodiments its food energy data is produced by processing PROm, Total_CHOm, DFm, Total_FATm, Sat_FATm, and ETOHm in the manner represented by the following equation:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×[Total_CHOm−DFm])+(Wdf×Cdf×DFm)+(Wfat×Cf×[Total_FATm−Sat_FATm])+(Wsfat×Cf×Sat_Fatm)+(Wetoh×Cetoh×ETOHm). (6)
The process represented by equation (6) is modified for use in CE and AU and is represented as follows:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×Total_CHOm)+(Wdf×Cdf×DFm)+(Wfat×Cf×[Total_FATm−Sat_FATm])+(Wsfat×Cf×Sat_Fatm)+(Wetoh×Cetoh×ETOHm). (7)
In certain embodiments, for foods containing sugar alcohol, the foregoing processes as represented by equations (6) and (7) are modified to add a term representing an energy component represented by the amount of sugar alcohol in the food. Where the amount of sugar alcohol (by weight or mass) is expressed in grams (represented as “SETOHm” herein), this term is produced by multiplying SETOHm by a weighting factor Wsetoh and a conversion factor Csetoh, where Wsetoh is selected from the range 0.9≦Wsetoh≦0.95, and in particular ones of such embodiments is substantially equal to 0.95, and Csetoh is selected from the range 0.2 to 4.0 kilocalories/gram, and in particular ones of such embodiments is substantially equal to 2.4. Where a food contains sugar alcohol, in certain embodiments its food energy data is produced by processing PROm, Total_CHOm, DFm, Total_FATm, Sat_FATm, ETOHm and SETOHm in the manner represented by the following equation:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×[Total_CHOm−DFm−SETOHm])+(Wdf×Cdf×DFm)+(Wfat×Cf×[Total_FATm−Sat_FATm])+(Wsfat×Cf×Sat_Fatm)+(Wetoh×Cetoh×ETOHm)+(Wsetoh×Csetoh×SETOHm). (8)
The process represented by equation (8) is modified for use in CE and AU and is represented as follows:
FED=(Wpro×Cp×PROm)+(Wcho×Cc×[Total_CHOm−SETOHm])+(Wdf×Cdf×DFm)+(Wfat×Cf×[Total_FATm−Sat_FATm])+(Wsfat×Cf×Sat_Fatm)+(Wetoh×Cetoh×ETOHm)+(Wsetoh×Csetoh×SETOHm). (9)
For the consumer's convenience, in many applications (such as the Weight Watchers® program) the food energy data is converted to simplified whole number data for a candidate food serving by producing dietary data expressed as whole number data by dividing the food energy data by factor data, such as data having a value of 35, and rounding the resulting value to produce the simplified whole number data. (Of course, to assign 35 as the value of the factor data is arbitrary, and any other value such as 50, 60 or 70 may be used for this purpose.)
In the manner described above, the consumer can easily track food consumption throughout a period, such as a day or a week, (either manually or with the assistance of a data processing system) to ensure that a predetermined sum of the dietary data for the food consumed bears a predetermined relationship to a value of predetermined whole number benchmark data based on one or more of the consumer's age, body weight, height, gender and activity level. For example, if the consumer is following a weight loss program, the predetermined whole number benchmark data is set at a value selected to ensure that the consumer will lose weight at a safe rate if he or she consumes an amount of food during the period having a sum of dietary data that does not exceed the predetermined whole number benchmark data.
Since individual food energy needs vary with the individual's age, weight, gender, height and activity level, in certain embodiments the predetermined whole number benchmark data is selected based on one or more of these variables. In such embodiments, food energy needs are estimated based on methods published by the National Academies Press, Washington, DC, USA in Dietary Reference Intakes for Energy, Carbohydrates, Fiber, Fat, Fatty Acids, Cholesterol, Protein and Amino Acids, 2005, pages 203 and 204. More specifically, as explained therein these methods estimate that men aged 19 years and older have a total energy expenditure (TEE) determined as follows:
TEE=864−(9.72×age)+PA×(14.2×weight+503×height), (10)
and that women aged 19 years and older have a TEE determined as follows:
TEE=387−(7.31×age)+PA×(10.9×weight+660.7×height), (11)
where age is given in years, weight in kilograms and height in meters.
In such embodiments, these methods are employed on the basis that all individuals have a “low active” activity level, so that the activity level (PA) for men is set at 1.12 and PA for women is set at 1.14. The published methods assume a 10 percent conversion cost regardless of the types and amounts of nutrients consumed; consequently, TEE is adjusted by subtracting 10 percent of the calculated TEE. Also, the published method of calculating TEE assigns an energy content of zero to certain foods having a non-zero energy content. The total energy content of such foods consumed within a given day generally falls within a range of 150 to 250 kilocalories, which may be normalized as 200 kilocalories. Accordingly, TEE as determined by the published method is adjusted to produce adjusted TEE (ATEE) in a process represented by the following equation:
ATEE=TEE−(TEE×0.10)+200, (12)
where ATEE and TEE are given in kilocalories.
For consumers carrying out a process of reducing body weight, the predetermined whole number benchmark is obtained by subtracting an amount from the adjusted TEE selected to ensure a predetermined weight loss over a predetermined period of time. For example, a safe weight loss process can be selected to produce a loss of two pounds per week, or a consumption of 1000 kilocalories per day less than ATEE for a given individual. In this example, to produce the predetermined whole number benchmark data (PWNB), where the factor data used to produce the dietary data for the candidate food servings (whether having a value of 35, 50, 60, 70 or other value) is represented as FAC, such data is produced by a process represented by the following equation:
PWNB=(ATEE−1000)÷FAC. (13)
To achieve weight loss, the value of (ATEE−1000) in certain embodiments is selected to fall within a range of 1000 kilocalories to 2500 kilocalories, so that if (ATEE−1000) is less than 1000 kilocalories, then (ATEE is set equal to 1000 kilocalories, and if (ATEE−1000) is greater than 2500 kilocalories, (ATEE−1000) is set equal to 2500 kilocalories. However, in various other embodiments, the upper limit of 2500 kilocalories varies from 2000 to 3000 kilocalories, and the lower limit of 1000 kilocalories varies from 500 to 1500 kilocalories.
Based on the obtained food energy data the consumer decides 30 whether to ingest the candidate food serving or to reject it. If the value of SUM would exceed predetermined maximum data if the consumer ingests the candidate food serving, the consumer decides 30 to reject it and the process returns to 20 to be repeated when the consumer again considers a candidate food serving for ingestion. If the consumer decides to ingest the candidate food serving, the food energy data is added 32 to SUM, the consumer ingests 36 the candidate food serving and the process returns to 20 to be repeated when the consumer again considers a candidate food serving for ingestion. It will be appreciated that steps 32 and 36 need not be carried out in the order illustrated.
Of course, if the consumer instead is attempting to gain body weight, then her or she selects and ingests candidate food servings within the period whose food energy data exceeds a predetermined benchmark.
Where system 40 is implemented as a PDA, laptop computer, desktop computer or cellular telephone, in certain ones of such embodiments the input 56 comprises one or more of a keypad, a keyboard, a point-and-click device (such as a mouse), a touchscreen, a microphone, switch(es), a removable storage or the like, and presentation device 60 comprises an LCD display, a plasma display, a CRT display, a printer, lights, LED's or the like.
In certain ones of such embodiments, storage 50 stores the necessary weighting data and conversion factor data necessary to carry out one or more of the processes summarized in equations (1) through (9) hereinabove. Using input 56, the consumer inputs the data PRO, CHO and FAT, the data PROm, CHOm and FATm, or the data PROm, Total_CHOm, DFm, Total_FATm, Sat_FATm, ETOHm (as available), and SETOHm (as available), for a food or candidate food serving depending on the process to be carried out. Processor 44 retrieves the necessary weighting data and conversion factor data, as need be, from storage 50 and processes the input data according to one of equations (1) through (9) to produce the food energy data. Processor 44 then controls presentation device 60 to display the food energy data to the consumer.
In certain ones of such embodiments, storage 50 stores food energy data for a plurality of predetermined foods, which can be retrieved using an address based on an identification of the food input by the consumer using input 56. Processor 44 produces an address for the corresponding food energy data in storage 50 and reads the food energy data therefrom using the address. Processor 44 then controls presentation device 60 to display the food energy data to the consumer.
In certain ones of such embodiments, the food energy data stored in storage 50 is downloaded from a server via a network. With reference to
In certain ones of such embodiments, processor 44 of one of data processing systems 40′ and 40″ receives the input data from input 56 and the consumer, and controls communications 64 to communicate such data to server 76 via network 70. Server 76 either retrieves the corresponding food energy data from a storage thereof (not shown for purposes of simplicity and clarity), or produces the food energy data from the received data using the weighting data and conversion data, as appropriate, and communicates the food energy data to communications 64. Processor 44 then controls presentation device 60 to display the food energy data to the consumer.
The systems of
In certain embodiments, processor 44 accesses appropriate instructions from storage 50 to produce a plurality of meal plans each designed to fulfill predetermined criteria, such as a weight loss diet, a weight gain diet, a weight maintenance diet, a low-fat diet, a low carbohydrate diet, an ethnically or religiously appropriate diet, or the like. Criteria and methods for producing such diets are well known and encompass the criteria and methods disclosed by US published patent application No. 2004/0171925, published Sep. 2, 2004 in the names of David Kirchoff, et al. and assigned to the assignee of the present application. US 2004/0171925 is hereby incorporated by reference herein in its entirety.
